NiTED OSCAR W. RICHARDSON, OF WORCESTER, MASSACHUSETTS, ASSIGNORTO CROlVI-PTON @a KNOWLES LOOM WORKS, OF "WORCESTER, MASSACHUSETTS, A CORPORATION 0F l MASSACHUSETTS.

Application led February To @ZZ whom t may cof/wem.'

Be it known that I, OsoAR W. RICHARD- soN, a. cit'zen of the United States, residing at Worcester', in the county of Worcester and State of Massachusetts, have invented a new and useful."vVeft-Carrier Magazine, of which the following is a specication.

This invention relates to a weft Vcarrier magazine for a weft replenishing loom and particularly to an improved device for preventing relative angular movement of the weft carriers while they are stored in the magazine compartments.

In such magazines, it has been found that the constant jar and vibration of the loom causes the weft carriers in storage to receive small intermittent rotational movements which have a tendency to entangle the weft ends, with a resultant weft breakage on transfer.

It is the object of my invention to prevent such angular movement of the weft carriers by the provision of a weighted follower for the weft carriers in each magazine compart- This follower frctionally engages the topmost weft carrier in the compartment and thus acts to hold all of the weft carriers in the compartment from rotation.

A further object of my invention is to provide convenient means by which each follower may be easily raised or withdrawn to permit replenishment of the magazine.

With these general objects in view, my invention consists in a certain arrangement and combination of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing in which- Fig. 1 is a sectionalside elevation of a weft carrier magazine taken along the line 1-1 in Fig. 2; l

Fg. 2 is a partial plan view of the parts shown in Fig. 1;

Fig. 3 is a sectional rear elevation taken along the line 3-3 in Fig. 1; and

Fig. 4 is a detail sectional side elevation taken along the line 4-4 in Fig. 2. y

Referring to the drawings, I have shown a stand or frame 10 constituting one end of a weft carrier magazine of the well-known statonary or multi-color type. The frame 10 is provided with a plurality of ribs or guideways 11 between which are formed compartments ,12 adapted to receive the butts WEET-CARRIER MAGAZINE.

of the weft carriers 7. These compartments are commonly vertically positioned and the weft carriers may be supported there'n by release plates 13 adapted to be moved longitudinally to release the lowermost weft carrier in a compartment when desired.

The parts thus far described are ofthe usual type and in themselves form no part of my present invention which relates particularly to the provision of a weighted follower 14 in each compartment adapted to frictionally engage the topmost weft carrier at the butt thereof and to prevent angular movement of the weft carrier.

For this purpose the follower 14 is provided with an engaging surface 15 preferably of the general outline shown in the drawings, with a wedge-shaped downwardly extending portion 16 engaging the weft carrier on its upper front face in such a manner as to force the weft carrier downward and also rearward against the rear wall 11 oI the compartment.

Each follower 14 is provided with a thin depending portion or plate 17 adapted to be positioned between the butts of the weft carriers W and the end of the compartment and to thus hold the weighted folrower from displacement.

A cord or chain 18 may be secured to each follower 14 and also to a ring or other fastening device 19 at the top of the frame 10. This chain 18 affords a convenient means by which the follower can be withdrawn from the compartment to permit replenishment thereof and also prevents the followers 14 from becoming lost when not in operative position.

It is found in practice that the frictional engagement of the topmost weft carrier by the wedge-like lower surface of the follower 14 effectively prevents rotation, not only of the weft carrier thus engaged, but also of all of the weft carriers in the compartment.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is 1. In a stationary magazine having substantially vertical weft carrier compartments, a weighted follower for each compartment effective to frictionally engage the topmost weft carrier in the compartment and to hold said'weft carrier from angrilai1 movement therein,l and means dependfng from the follower and engaging a portion offthe Yloobloin therennderto prevent lateral displacement of said follower.

2. In a stationary magazine having substantially vertical weft carrier Compartments, a'weighted follower for each compartment having a portion frietionally engaging the loiitt of the topinost weft Carrier in the eompartinent,` and a perton extendingy downward adjacent the end of the weft Carrier, hywhioh latter portion said follower is VheldY from lateral displacement.

Ina stationary magazine having suhstantially vertical weft carrier compartments, a. weighted follower for each coinpaiitnielitifhaving a. portion frietionally engagingw the top and one side of the butt of the topmost weft Carrier in the compartment and being effective to force the weft carrier downward and also laterally of the compartment against one side wall thereof. 4l. In a stationary magazine having suhstantially vertical weft carrier Compartinents, a weighted follower for each oompartment havinga. portion frlotionally engaging an upper and side portion of the butt of the topmost weft carrier in the oom.- partinent, and being efleetive to force the weft carrier downward and also laterallyIv of the Con'ipartment against one side wall thereof, and means to hold said follower from dsplaoement.

lrn testimony whereof I have hereunto affixed my signature.
